Patent JP-H01320805-A (JP)
Title: Amplifier circuit
Inventor: MAKABE TAKAYOSHI
IPC: H03F3/34
Filed: 1988-06-22
Abstract: PURPOSE:To obtain a large voltage gain with saved space by providing 1st and 2nd transistors(TRs) and constituting a positive feedback circuit by 3rd to 6th TRs together with the 2nd TR. CONSTITUTION:The 1st MOS TR 11 acts like a drive TR and the 2nd TR 12 acts like a load TR. With a gate input voltage VIN of the TR 11 increased, an output voltage VOUT is lowered and the source potential of the TR 12 is also decreased. Then the gate-source voltage of the TR 16 is increased and the source potential and the gate voltage of the TR 15 rise. Thus, the drain current of the TR 12 is decreased and the output voltage VOUT is further decreased. The TRs 12 to 16 constitute a positive feedback circuit in this way. The voltage gain Av is expressed in equation. Then since gm12/gm13 is sufficiently increased when a channel width W13 of the TR 13 and a channel length L12 of the TR 12 are selected sufficiently smaller, the voltage gain Av is increased without increasing the chip size.

Title: Object recognition device
Inventor: YAMAMOTO KATSUMI
IPC: G01B11/00
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To provide an object recognition device which can properly detect a work. SOLUTION: The image data outputted from a CCD camera are inputted (S102) and vertically scanned (S104). Then a shaft is detected based on the lightness corresponding to a section shape (S106, S112 and S114). The detected shaft is horizontally traced (S116), and the edge part of a work is detected based on the continuity of brightness corresponding to the section shape (S118). Finally, the longest work, i.e., a work that is not set under other works is detected based on the detected work edge part and outputs the detected work to a robot controller (S126). In this example, the work edge part is detected following a local feature part and accordingly the work is not easily affected by the change of lightness of an entire screen and the local chance of illumination. Thus, the work is correctly recognized.

IPC: B41J2/045
Filed: 1981-09-30
Abstract: PURPOSE:To facilitate the adjustment of the velocity of ink particles so that the slide of dot position be 1/n of an inter-dot distance, by deciding the range of the velocity of the ink particles based on a frequency of turning ink into particles and on a distance between a nozzle and recording paper, and by performing the adjustment within the range. CONSTITUTION:When the relations of a particle velocity V, a frequency f of turning ink into particles, a distance D between a nozzle 3 and recording paper 4, and a reference particle velocity Vd  which is a particle velocity determining a reference dot position are expressed by the formulas 1 and 2, the slide of the dot position can be limited within + or -1/n of an inter-dot distance in relation to the reference dot position at the reference particle velocity Vd. This range of the particle velocity can be obtained within the formulas 1 and 2 on conditions of V>=0 and f<=Vd/nd. Accordingly, when the particle velocity is adjusted within this range, any ununiformity in the particle velocity is permissible, and thus the adjustment of the velocity is made easy.

Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To correctly access an optical head to a target track by compensating for an error of a movement speed of the optical head to an optimum speed profile which is brought about when a set driving shaft of the optical head is inclined with respect to a horizontal direction. SOLUTION: When an inclination of an optical head 2 is detected from a lens position error signal of an objective lens 3, a speed profile of the optical head 2 is corrected in accordance with a size and a direction of the inclination, thereby controlling a movement of the optical head 2. When the optical head 2 moves in a direction to rise (descend) an inclined face, a movement speed of the optical head 2 is accelerated to a speed determined in accordance with an inclination amount of the optical head 2 and a deceleration control is started at a predetermined time point determined in accordance with the inclination amount (to raise a speed starting a constant speed control to a predetermined speed determined according to the inclination amount).  A movement distance lacking (exceeding) because of an application of a gravity acceleration component in a deceleration (acceleration) direction is compensated for.
